President Milei's Nuclear Ambitions Face Local Resistance in Patagonia

Argentina's Uranium Ambitions Meet Resistance

Argentina has emerged as a focal point for global mining firms, drawn by its substantial reserves of critical minerals and a history of mining activity. Beyond lithium and copper, uranium deposits are attracting considerable attention, particularly as numerous nations accelerate their nuclear energy programs. However, the prospect of expanded uranium extraction has generated apprehension among many Argentinians, sparking debates over resource management and environmental stewardship.

The nation's estimated uranium resources amount to approximately 10,500 tonnes of elemental uranium (tU). Exploration efforts began in the 1950s, but the last uranium mine ceased operations in 1997 due to economic factors. Cumulative national uranium production up to that point totaled around 2,582 tU. Despite this history, a resurgence in uranium mining is far from assured.

Economic Strategy vs. Local Concerns

Argentina operates three nuclear power plants Atucha I and II, and Embalse that collectively supply about 5 percent of the country's electricity. Since the closure of its uranium mines, Argentina has relied on imports to meet its uranium requirements. President Milei views the revival of the domestic uranium mining industry as a strategic imperative to enhance energy independence and bolster the national economy.

The Sierra Pintada mine in Mendoza, operated by the National Atomic Energy Commission (CNEA), was slated for reopening, but provincial opposition has stalled progress. Similarly, a 2007 agreement between CNEA and the Salta provincial government to develop the Don Otto uranium mine, which operated from 1963 to 1981, has not materialized. These setbacks underscore the challenges in navigating local sentiment and regulatory hurdles.

Since 2018, CNEA has been evaluating the feasibility of mining the Cerro Solo deposit in Chubut, estimated to contain 4600 tU, positioning it as one of Argentina's largest known uranium reserves. However, a provincial ban on open-pit mining adds another layer of complexity. Redeveloping this mine represents a key component of President Milei's nuclear energy strategy. The success of this endeavor hinges on addressing environmental concerns and securing community support.

Export Focus and Patagonian Perspectives

Opposition to Milei's nuclear agenda stems from various factors. Former CNEA president Adriana Serquis suggests that:

"The plan doesn’t seem oriented toward supplying our own plants, but rather exporting uranium directly to the U.S. It would appear the objective is to satisfy others’ needs while destroying our own capabilities."

Adding to the controversy, Dioxitek, a state-owned subsidiary of CNEA, entered into an agreement with U.S.-based Nano Nuclear Energy to supply uranium hexafluoride, a compound not directly used in Argentina's existing nuclear reactors. This development fuels speculation that any uranium mined domestically would primarily be destined for export to the United States.

Nano also signed an agreement with UrAmerica, a British-Argentinian company with interests in Chubut, to secure materials for nuclear fuel. The agreement explicitly mentions "strengthening U.S. energy security by sourcing materials for nuclear fuel from a reliable partner".

Considering Argentina's estimated uranium reserves could potentially meet domestic demand for approximately 70 years based on current consumption, some industry observers question the rationale for prioritizing exports over national energy production. Milei's approach aligns Argentina more closely with the United States, reinforcing his declaration of Argentina as an "unconditional ally of the U.S.".

Residents of Chubut express apprehension about becoming an energy colony, citing past disappointments and environmental risks associated with uranium mining and waste disposal. A 2003 referendum rejecting open-pit gold mining by an 81 percent margin led to the enactment of legislation prohibiting such practices. Communities in Chubut voice feelings of neglect, living near the remnants of previous, unsuccessful uranium mining ventures.

A visit by a U.S. Congressional delegation to Neuquén to discuss critical mineral mining, along with an earlier stopover in Ushuaia, has heightened concerns about U.S. interest in the Patagonian region. The presence of uranium and rare earths in Tierra del Fuego and exploration projects in Chubut have fueled speculation about potential exploitation of the area's resources, raising environmental and social implications.
